The Role of Artificial Neural Networks in Data Mining and Analytics

Artificial Neural Networks (ANNs) have revolutionised data mining, enabling organizations to uncover hidden patterns and relationships within complex data sets. Inspired by the human brain’s neural structure, ANNs mimic cognitive functions to analyze and interpret vast amounts of data.

What are Artificial Neural Networks?

ANNs are computational models comprising interconnected nodes (neurons) that process inputs, transform data, and produce outputs. Each node applies non-linear transformations, allowing ANNs to learn and adapt.
